BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a display. More particularly, thepresent invention relates to a touch panel display.

2. Description of Related Art

Recently, with quick development of information and wirelesscommunication technologies and the widespread of various informationproducts, the conventional input devices (for example, a keyboard or amouse) of many information products have been replaced by touch panelsin order to make these information products more convenient, compact,light-weighted, and personalized, wherein the touch panel is combinedwith a display to form a touch panel display. The touch panels ofnowadays are approximately classified into resistive touch panels,capacitive touch panels, optical touch panels, acoustic wave touchpanels and electromagnetic touch panels according to a design thereof.

Regarding the resistive touch panel, originally separated conductivelayers are contacted and electrically connected due to pressure, so thata voltage drop is generated at the press position. By measuring aposition of the voltage drop, coordinates of the press position on thetouch panel are determined. Regarding the capacitive touch panel, auniform electric field is generated at inner and outer conductivelayers, so that when a conductor (for example, a user's finger) contactsthe touch panel, an electrostatic binding is occurred to generate a tinycapacitance variation. By measuring a position of the capacitancevariation, the coordinates of the press position on the panel aredetermined.

FIG. 1A is a top view of a conventional touch panel display, and FIG. 1Bis a cross-sectional view of the touch panel display of FIG. 1A along aline I₁-I₁′. Referring to FIG. 1A and FIG. 1B, the conventional touchpanel display 100 includes a first substrate 110, a second substrate120, a touch device 130, a liquid crystal layer 140 and a sealant 150.

As shown in FIG. 1B, the sealant 150, the first substrate 110 and thesecond substrate 120 form a cell, i.e. a closed spacer, to accommodatethe liquid crystal layer 140 therein. The first substrate 110 has adisplay area A and a peripheral area B, wherein a pixel array 112 islocated at the display area A, and a gate driving circuit 114 and asource driving circuit 116 are located at the peripheral area B.Moreover, the gate driving circuit 114 is electrically connected to scanlines (not shown), and when the gate driving circuit 114 outputs a scansignal that is sufficient to turn on a thin film transistor (TFT, whichis not shown) to the TFT, the TFT is turned on, at the same time, thesource driving circuit 116 can input a data signal to a pixel unit (notshown) through a data line (not shown).

The second substrate 120 and the first substrate 110 are respectivelylocated at two sides of the liquid crystal layer 140, and the touchdevice 130 is disposed on the second substrate 120. Moreover, the touchdevice 130 includes a sensor element 132, a wiring element 134 and aconnecting terminal 136, wherein the wiring element 134 is electricallyconnected to the connecting terminal 136. In detail, the sensor element132 includes a plurality of sensor units 132 a, and the wiring element134 includes a plurality of X bus-lines 134 a electrically connected tothe sensor units 132 a, and a plurality of Y bus-lines 134 belectrically connected to the sensor units 132 a. Therefore, when theuser touches the touch device 130, the X bus-lines 134 a and the Ybus-lines 134 b can transmit the sensing signal to a controller (notshown) through the connecting terminal 136, so as to calculate anX-coordinate and a Y-coordinate of the touch position.

However, in order to cater to a relatively large display area and designrequirements of light and slim, and a narrow border, the space of theconventional touch panel display 100 that is used for the wiring element134 layout is limited. Therefore, the resistance of the wiring element134 is increased due to an inadequate line width d₁, which may lead todelay and distortion for transmitting the sensing signal, andaccordingly influences the operation sensitivity of the conventionaltouch device 130. Moreover, the units number of the sensor element 132and the lines number of wiring element 134 are also limited, so that thetouch resolution of the touch device 130 is confined. In addition, theconnecting terminal 136 is preferably disposed at a side opposite to thegate driving circuit 114 and the source driving circuit 116, so as toavoid influencing a follow-up bonding process of the other electroniccomponents and to meet mechanical design requirements. Obviously, adesign flexibility of a position of the connecting terminal 136 of thetouch device 130 in the conventional touch panel display 100 is notenough.

DESCRIPTION OF THE EMBODIMENTS First Embodiment

FIG. 2A is a top view of a touch panel display 200 according to thefirst embodiment of the present invention, and FIG. 2B and FIG. 2C arecross-sectional views of the touch panel display of FIG. 2A along a lineI₂-I₂′. Referring to FIG. 2A and FIG. 2B, the touch panel display 200 ofthe present embodiment includes a first substrate 210, a secondsubstrate 220, a touch device 230, a display medium 240 and a sealant250 a. A size of the first substrate 210 is greater than that of thesecond substrate 220. In detail, a width of the second substrate 220 isless than that of the first substrate 210, and a length of the secondsubstrate 220 is substantially the same to that of the first substrate210. Moreover, the sealant 250 a and the two substrates 210 and 220 forma closed space to close the display medium 240 therein. In addition, thedisplay medium 240 includes, for example, a liquid crystal layer, anorganic light emitting material layer or an electrophoretic displaymaterial layer. The first substrate 210 is, for example, a thin filmtransistor (TFT) array substrate, which includes a lower substrate, aplurality of scan lines, a plurality of data lines, a plurality of TFTs,a plurality of pixel electrodes, and a peripheral circuit, etc.

As shown in FIG. 2B, the first substrate 210 has a display area D and aperipheral area E, and has a pixel array 212 in the display area D, andat least one integrated driving circuit 214 in the peripheral area E,wherein the integrated driving circuit is located below the secondsubstrate 220, and is electrically connected to the pixel array 212. Thepixel array 212 includes a plurality of the scan lines (not shown), aplurality of the data liens (not shown) and a plurality of pixel units(not shown), wherein each of the pixel units is, for example consistedof a TFT, a pixel electrode and a storage capacitor. The TFTs areelectrically connected to the scan lines and the data lines, and each ofthe pixel electrodes is electrically connected to the corresponding TFT.

In the present embodiment, the integrated driving circuit 214 is, forexample, a gate driver on array (GOA), which is connected to the scanlines. When the integrated driving circuit 214 outputs a scan signalthat is enough to turn on a TFT (not shown) to the TFT, the TFT isturned on. Now, the source driving circuit 216 can input an image signalto the pixel unit through the data line.

As shown in FIG. 2B, the second substrate 220 is disposed above thefirst substrate 210, and covers at least a portion of the integrateddriving circuit 214 and the pixel array 212. Moreover, the secondsubstrate 220 of the present embodiment is, for example, a color filtersubstrate mainly including a black matrix (not shown) and a plurality ofcolor filters (not shown), wherein the color filters are, for example,color filters of different colors such as red, green and blue, etc.

The display medium 240 is disposed on the pixel array 212, and islocated between the first substrate 210 and the second substrate 220. Asshown in FIG. 2A and FIG. 2B, the touch device 230 is disposed on thesecond substrate 220, and includes a sensor element 232 and a wiringelement 234. In detail, the sensor element 232 is located above thepixel array 212, and a part of the wiring element 234 is located abovethe integrated driving circuit 214. Moreover, in the present embodiment,the second substrate 220 further includes an upper substrate and acommon electrode, wherein the common electrode is disposed on the blackmatrix and a surface of the color filters. Moreover, the touch device230 and the common electrode are respectively located at two oppositesides of the upper substrate.

It should be noticed that in FIG. 2B, though the wiring element 234 islocated above the integrated driving circuit 214, in other embodiments,the integrated driving circuit 214 can be not totally covered by thewiring element 234. In other words, the wiring element 234 is onlylocated above a portion of the integrated driving circuit 214. Moreover,a thickness of the integrated driving circuit 214 is between 0.1 um to100 um.

In addition, the sensor element 232 is electrically connected to thewiring element 234. The sensor element 232 is mainly composed of aplurality of sensing units 232 a, and the wiring element 234 includes aplurality of X bus-lines 234 a and a plurality of Y bus-lines 234 b. Asshown in FIG. 2A, the touch device 230 further includes a connectingterminal 236, and the connecting terminal 236 can be located at any edgeof the second substrate 220. In the present embodiment, the connectingterminal 236 is located at a long side S₂ of the second substrate 220.Therefore, when the user touches the touch device 230, the X bus-lines234 a and the Y bus-lines 234 b can transmit the sensing signal to acontroller (not shown) through the connecting terminal 236, so as tocalculate an X-coordinate and a Y-coordinate of a press position.

It should be noticed that since the integrated driving circuit 214 canbe formed integrally with the pixel array 212, and compared with aconventional driving circuit, the integrated driving circuit 214 has arelatively thin thickness, the second substrate 220 can extend outsideto cover the integrated driving circuit 214, so as to increase a spaceof the second substrate that is used for configuring the wiring element234 (especially the Y bus-lines 234 b). Accordingly, when the wiringelement 234 has a relatively great configuration space, restriction of aline width (for example, a line width d₂ of the Y bus-line 234 b) of thewiring element 234 in the configuration space is mitigated. In case thatthe line width of the wiring element 234 is not greatly restricted, aresistance of the wiring element 234 is reduced, so that a strength ofthe sensing signal is increased.

Moreover, referring to FIG. 2A to FIG. 2C, FIG. 2C is similar to FIG.2B, and a difference there between is that a quantity of the wiringelement 234 of FIG. 2C is more than a quantity of the wiring element 234(especially the Y bus-lines 234 b) of FIG. 2B. In detail, in the touchpanel display 200 of FIG. 2C, a touch resolution of the touch device 230is increased as the quantity of the Y bus-lines 234 b is increased.Therefore, to configure more Y bus-lines 234 b in the same configurationspace, a line width d₃ of the Y bus-line 234 b of FIG. 2C is smallerthan the line width d₂ of the Y bus-line 234 b of FIG. 2A. A reductiondegree of the line width d₂ is determined according to a requirement ofthe touch resolution. However, it should be noticed that compared to theconventional wiring element 134, since the wiring element 234 of FIG. 2Cis relatively wider (i.e. d₁<d₃), the wiring element 234 still hasrelatively low resistance compared with that of the conventional wiringelement 134, so that the sensing signal may have relatively greatstrength. Moreover, since the quantity of the wiring element 234 isincreased, the touch panel display 200 of the present embodiment hashigher touch resolution compared with that of the conventional touchpanel display 100.

It should be noticed that in the present embodiment, though theintegrated driving circuit 214 is GOA, and the second substrate 220extends along the horizontal direction to cover at least a portion ofthe GOA, in the other embodiments, the integrated driving circuit 214can further be a source driver on array (SOA), and now the secondsubstrate 220 extends along the vertical direction to cover at least aportion of the SOA.

In the following embodiments and drawings, the same or like referencenumerals refer to the same or the like elements, so as to simplify thedescription.

Second Embodiment

FIG. 3A is a top view of a touch panel display 300 according to thesecond embodiment of the present invention, and FIG. 3B is across-sectional view of the touch panel display of FIG. 3A along a lineI₃-I₃′. Referring to FIG. 3A and FIG. 3B, the touch panel display 300 ofthe present embodiment is similar to the touch panel display 200 of thefirst embodiment, and a difference there between is that the connectingterminal 236 of the present embodiment is located at a short side S₃ ofthe second substrate 220. Namely, the wiring element 234 may protrudeout pins at the short side S₃ of the second substrate 220. In otherwords, as shown in FIG. 3B, the integrated driving circuit 214 islocated between the pixel array 212 and the connecting terminal 236.

In detail, compared to the conventional driving circuit, since athickness of the integrated driving circuit 214 of the presentembodiment is relatively thin, the second substrate 220 can extendoutside to cover at least a portion of the integrated driving circuit214 to increase the space of the second substrate 220 that is used forconfiguring the wiring element 234, so that the wiring element 234 mayhave enough space at an area F, and the X bus-lines 234 a and the Ybus-lines 234 b can all protrude out from the short side S₃. Therefore,a position and a quantity of the connecting terminal 236 can be flexiblychanged, so that the touch panel display 300 can be flexibly usedtogether with designs of dual-side driving, tri-side driving orquadri-side driving.

FIG. 4A is a top view of a touch panel display 400 according to thethird embodiment of the present invention, and FIG. 4B is across-sectional view of the touch panel display of FIG. 4A along a lineI₄-I₄′. Referring to FIG. 4A and FIG. 4B, the touch panel display 400 ofthe present embodiment is similar to the touch panel display 300 of thesecond embodiment, and a difference there between is that the integrateddriving circuit 214 of the touch panel display 400 of the presentembodiment includes at least one GOA 214 a and at least one SOA 214 b.Therefore, the second substrate 220 can not only extend along thehorizontal direction but can also extend along the vertical direction torespectively cover at least a portion of the GOA 214 a and at least aportion of the SOA 214 b. By such means, the space on the secondsubstrate 220 that is used for configuring the wiring element 234 islarger than that of the first and the second embodiment, so that thequantity of the wiring element 234 can be increased to increase thetouch resolution of the touch device 230. Moreover, as shown in FIG. 4B,since the space on the second substrate 220 that is used for configuringthe X bus-lines 234 a is enlarged, the user can also selectively widen aline width d₄ of the X bus-line 234 a, so as to reduce the resistance ofthe X bus-lines 234 a to increase the strength of the sensing signal.

It should be noticed that in the present embodiment, though a size ofthe first substrate 210 is greater than that of the second substrate220, in other embodiments, the size of the first substrate 210 can alsobe substantially the same to that of the second substrate 220.

Fourth Embodiment

FIG. 5A is a top view of a touch panel display 500 according to thefourth embodiment of the present invention, and FIG. 5B is across-sectional view of the touch panel display of FIG. 5A along a lineI₅-I₅′. Referring to FIG. 5A and FIG. 5B, the touch panel display 500 ofthe present embodiment is similar to the touch panel display 200 of thefirst embodiment, and a difference there between is that the secondsubstrate 220 is, for example, a transparent substrate, and the touchdevice 230 (shown in FIG. 5A) is located on an upper surface of thetransparent substrate. Moreover, a third substrate 260 of the presentembodiment is, for example, a color filter substrate.

As shown in FIG. 5B, in the present embodiment, the second substrate 220is disposed on the third substrate 260, and the touch device 230 isdisposed on the second substrate 220. Namely, the touch panel display500 of the present embodiment is an out-attached touch panel display,and the touch panel displays 200-400 of the first to the thirdembodiments are built-in touch panel displays.

Fifth Embodiment

FIG. 6A is a top view of a touch panel display 600 according to thefifth embodiment of the present invention, and FIG. 6B is across-sectional view of the touch panel display of FIG. 6A along a lineI₆-I₆′. Referring to FIG. 6A and FIG. 6B, the touch panel display 600 ofthe present embodiment is similar to the touch panel display 500 of thefourth embodiment, and a difference there between is that the secondsubstrate 220 of the touch panel display 600 of the present embodimentis, for example, a transparent substrate, and the touch device 230(shown in FIG. 6A) is configured on the second substrate 220, and islocated at a lower surface of the transparent substrate. An advantage ofsuch configuration is that the second substrate 220 can serve as aprotection cover for the touch device 230.

Sixth Embodiment

FIG. 7 is a cross-sectional view of a touch panel display 700 accordingto the sixth embodiment of the present invention. The touch paneldisplay 700 of the present embodiment is similar to the touch paneldisplay 200 of the first embodiment, and a difference there between isthat the display medium 240 of the touch panel display 700 of thepresent embodiment is a liquid crystal layer, and the touch paneldisplay 700 further includes a backlight module 280.

As shown in FIG. 7, the backlight module 280 is disposed below the firstsubstrate 210 to provide a light source (not shown) to the liquidcrystal layer 240. Moreover, the touch panel display 700 furtherincludes polarizers 270 a and 270 b respectively disposed on the firstsubstrate 210 and the second substrate 220, so as to polarize the lightpassing there through.

In summary, since the touch panel display of the present invention hasat leas one integrated driving circuit, which can be fabricatedintegrally with the pixel array and has a relatively thin thicknesscompared to that of the conventional driving circuit, the uppersubstrate can extend outside to cover the integrated driving circuit, sothat a wiring element configuration space of the touch device isincreased. When the wiring element layout space of the touch device isincreased, the quantities of the units of the sensor element and thelines of the wiring element are increased, so that the touch resolutionof the touch panel display is increased. Moreover, restriction of theline width of the wiring element is mitigated, and accordingly aresistance of the wiring element is reduced, and the strength of thesensing signal is increased.
